Summary: EA series ultrasonic material (liquid) level meter is a kind of intelligent non-corroded material (liquid) level measuring instrument. The product has automatic power adjustment, gain control, temperature compensation, advanced detection technology and calculation technology, improves the measurement accuracy of the instrument, inhibits the interference echo, and ensures the accuracy of the measurement results. The product can be widely used in all kinds of liquid level and solid level measurement. Also can be used for distance measurement. Advantage: 1. Circuit design selects high-quality power module from the power supply part, and the components are highly stable and reliable imported from Germany, which can completely replace imported instruments of the same type from abroad 2. The patented acoustic intelligent technology software can perform intelligent echo analysis without any debugging or other special steps. This technology has the function of dynamic thinking and dynamic analysis. 3. The acoustic intelligent patent technology owned by our company greatly improves the accuracy of the instrument, and the liquid level accuracy reaches 0.3%, which can resist all kinds of interference waves 4. All the input and output lines of the meter have the function of lightning protection and short circuit protection 5. The instrument display screen can be added with backlight display (patented technology), so that the display of the meter head can be clearly seen at night, and the instrument display can be clearly seen under strong sunlight 6. Programmable relay output: the relay is programmable, and each relay can be set to high or low alarm or close Product features: • adopt SMD technology to improve instrument reliability. • automatic power adjustment, gain control, temperature compensation. • advanced detection technology, rich software functions to adapt to a variety of complex environments. • adopt new waveform computing technology to improve the measurement accuracy of the instrument. • the suppression function of interference echo ensures the authenticity of measurement data. • 16-bit D/A conversion to improve the accuracy and resolution of current output. • the sensor is made of tetrafluoroethylene. Can be used in a variety of corrosive occasions. • multiple output forms: programmable relay output, high accuracy 4-20ma current • output, RS485 digital communication output Main parameters: Power supply: AC220V, DC24V Analog output: 4-20ma, two-wire system (four-wire system optional, relay output optional) Digital output :RS485,Modbus protocol or custom protocol Range: 0-20 m Speech area: 0.3 to 0.6 m Accuracy: 0.25%, 0.5% Ambient temperature: - 25 ℃ to 55 ℃ Protection level: IP65 Resolution: range is less than or equal to 15m: 1mm >15m： 1cm Display mode: 16-bit x2LCD backlight
